Are these Longines watches authentic?

Hi there,
I'm very new here and I've been looking through a lot of the pictures on here to spot a fake but I'm having a hard time with a few of them to be honest.
Could someone give me some feedback on these Longines on ebay?
I'm pretty sure the second one is redial? Very odd number placement I would think and no model name?
not so sure about the conquest though. Any thoughts?
Thanks in advance!
